Answer:
15 dollars per hour
Step-by-step explanation:
She is constantly charging 15 per hour.
The first given equation is:
4x + 3y = 6
which can be rewritten as:
2(2x) + 3y = 6 .............> equation I
The second given equation is:
2x + 2y = 5
which can be rewritten as:
2x = 5 - 2y ........> equation II
Substitute with equation II in equation I to get the value of y as follows:
2(5-2y) + 3y = 6
10 - 4y + 3y = 6
-y = 6-10 = -4
y = 4
Substitute with the y in equation II to get x as follows:
2x = 5 - 2y
2x = 5 - 2(4)
2x = 5 - 8 = -3
x = -3/2
From the above calculations:
x = -3/2
y = 4
Answer for the first blank: median
Answer for the second blank: centroid
Answer:
x=20
Step-by-step explanation:
sum of all the sides is equal to 180degrees
group like terms
solve the question
The answer is 1 because A is -3 and B is -1 and c is 1 and then D is 4
